Pipe is being closed. Trying to pass request body to php process

I found the main issue. The script sets the header location and this is not supported. I have removed the php script and replaced it with html/js + api. Thanks for help. Even we havnt found a solution I have learned few new things. The solution (havnt tried yet) is to call the fastcgi service e.g. php-fpm, but there is no active maintained wrapper for .net

Pipe is being closed. Trying to pass request body to php process

Process.Start() returned true. I have moved over to CliWrap. Thats my code. Sadly same result, blank screen while executing a script with a body

private async Task ExecutePhpFileAsync(HttpContext context, string filePath)
{
    try
    {
        Dictionary<string, string?> environmentVariables = new()

Pipe is being closed. Trying to pass request body to php process

@occluder Like this?

if (context.Request.ContentLength > 0 || context.Request.ContentType != null)
{
    using MemoryStream memoryStream = new();
    await context.Request.Body.CopyToAsync(memoryStream);
    memoryStream.Seek(0, SeekOrigin.Begin);

    await phpProcess.StandardInput.BaseStream.WriteAsync(memoryStream.ToArray(), 0, (int)memoryStream.Length);
    await phpProcess.StandardInput.FlushAsync();
}

if (context.Request.ContentLength > 0 || context.Request.ContentType != null)
{
    using MemoryStream memoryStream = new();
    await context.Request.Body.CopyToAsync(memoryStream);
    memoryStream.Seek(0, SeekOrigin.Begin);

    await phpProcess.StandardInput.BaseStream.WriteAsync(memoryStream.ToArray(), 0, (int)memoryStream.Length);
    await phpProcess.StandardInput.FlushAsync();
}

Same exception

The pipe is being closed.

Publish Failure of Class Library with WinAppSdk dependency

I added the flag to publish WinAppSdk in self-contained mode in the .csproj of the class library. Now I'm encountering the error:

error : The platform 'AnyCPU' is not supported for Self Contained mode.

error : The platform 'AnyCPU' is not supported for Self Contained mode.

This issue is puzzling because the platform is indeed set to win-x64.
